SEAT FOR AGRICULTURAL MACHINES.

Specification of Letters Patent.

Patented Jan. 19, 1909;

Application filed November 11, 1905. Serial No. 286,838.

To all whom it may concern:

Be it known that I, GUSTAVE F. DANIEL son, a citizen of the UnitedStates of Amen ica, residing at Youngstown, in the county of Mahoningand State of Ohio, have invented certain new and useful Improvements inSeats for Agricultural Machines, of which the following is aspecification, ref erence being had therein to the accompanyingdrawings.

This invention has special reference to a universal reinforcement platefor that class of seats which are made of sheet steel and are mountedupon spring bars and the invention consists in the novel construction ofthe reinforcing plate and of the part of the seat to which it isapplied, with the object in View to make a light and strong seat and atthe same time adapt the same seat to be mounted without any change ofconstruction upon spring bars of different width, all as more fullyhereinafter described and shown in 'the accompanying drawings, in which-Figure 1, is a plan view of a seat of my construction as it appearslooking at the underside thereof; Fig. 2, is a section on line a*w Fig.1 showing it as it appears in position when mounted upon a spring bar;Fig. 3, is a cross section on line ;z y in Fig. l, the section beingbottom side up same as in Fig. 1; Fig. at, a section taken on line 2-2of Fig. 1 of the reinforcing plate alone, as in the actual positionbelow the seat; 5, is a detached perspective View of a reinforc ingplate of a modified construction, the view being that of its underside;Fig. 6, is an edge elevation of Fig. 5, and Fig. 7, is a cross sectionof one corner of the plate on line ww in Fig. 5.

In the drawings A is the seat, 13 is the reinforcing plate, C is thespring arm upon which it is mounted and D is the bolt which detachablysecures the seat upon the spring arm. The seat is as usual made of asheet of steel pressed into shape, it is made with a square hole a inthe center for the bolt to pass through and around this hole an annularcorrugation b is formed for the purpose of strengthening the seat aroundthe bolt and to form a depression for the head of the bolt to lie in.The seat is fur ther formed with a number of tubular rivets usually fourwhich are integrally drawn from the material of the seat and projectdownwardly and form the means for securing the reinforcing plate to theunderside of the seat.

The reinforcing plate B consists of a piece of sheet steel shaped tofitsnugly against the underside of the seat it has a corresponding hole inthe center for the seat bolt and corresponding holes for the rivets ofthe seat which pass through the holes and are headed upon the undersideof the reinforcing plate. As the seat is secured upon the spring armonly by the single bolt D, means are provided to prevent the seat fromturning upon this bolt and to this end I provide the reinforcing platewith projections upon its underside to confine the spring laterally andthese projections I arrange upon a novel manner with the object in Viewto accommodate the seat to be fastened upon spring arms of differentwidth.

As shown in Figs. 1% the projections are formed by cutting slits in theplate parallel to the longitudinal axis of the seat and then bulging outthe severed portions of the plate to form four groups of projections e fg in such manner that the projections 6 will accommodate between them aspring arm of the smallest size in use, the next adjacent projections fare made to project further out from the plate and accommodate a springarm of the next larger size and the outermost projections g are bulgedout still further and accommodate between them a spring arm of thelargest size in use which is ordinarily three inches wide. As the headsof the rivets c slightly project below the bearing face of thereinforcing plate and would therefore give the smallest sized spring arm(which fits between the projections 0) an insecure bearing on the plate,I bend a portion of the edges of the plate slightly out of line to formlips 71 thereon in such a manner as to form bearings for the spring armas more particularly shown in Fig. 2, in which the dotted linesrepresent a spring arm of the smallest size. The spring arm which fitsbetween the projections f has its bearing upon the projections c and theone which fits between the projections g has its bearings upon theprojections f and these spring arms thus have a secure bearing on theseat.

On accountof the difference in the sizes of the spring arms used ondifferent machines or by different makers of agricultural machines, themanufacturer of agricultural seats was obliged heretofore to make andkeep in stock a separate seatfor each size, but with my presentinvention Ihave done away with this as one seat can be used for any ofthe difierent sizes in use, which is a benefit to the manufacturer aswell as the maker of agriculturalmachinery. There is yet another pointinvolved in my invention and this lies in the adaptability of my seat tobe mounted upon a spring arm which is secured transversely instead oflongitudinally as in most of the agricultural machines.

It will be readily seen that a spring arm of suitable width may besecured transversely as well between the groups of projections, suitablelips it being also formed on the lateral edges of the reinforcing plateto form a bearing for each spring arm instead of letting them bear onthe rivet heads which would not be quite so secure. There is thislimitation however that but one size of s ring arm could be used in thetransverse direction, but by a modification in forming the projectionson the reinforcing plate, I can provide a seat which is adapted to bemounted upon three sizes of spring arms in either the longitudinal or inthe transverse direction of the seat. This modification shown in Figs.5, 6 and 7, is in all essentials like the one shown in Figs. 14 exceptas to the projections which are in the form of triangular spurs ofdifferent sizes respectively of different height and arranged in adifferent manner. Thus the spurs 2' z" are of the least height andaccommodate between them the smallest size of spring arm. There are twosets of these one i for a longitudinal and the other z" for a transversespring arm,

the spurs j j project further out and there is but one set adapted toaccommodate a spring arm of the next largest size in either directionand the spurs project still further and the one set will accommodate thelargest sized spring arms in either direction.

My invention thus broadly consists in providing a seat with areinforcing plate which provides a universal adjustment for all sizes ofsprings or conditions of use, which permits the manufacturer in shippingout a car load of machinery comprising spring bars of assorted sizes, toship only so many seats of one kind as there are spring bars and thusavoid confusion and mix up, as a resultof having each seat fit but onesize of supporting bar.

Having thus fully described my invention, what I claim is 1. Areinforcing plate for an agricultural seat provided upon opposite sidesof its longitudinal center line with projections of Varying height andof varying distances from said line corresponding to the different widthof springs for the support of the seat, their height increasing withtheir distance from the center line, those having the same distancebeing of the same height.

A reinforcing plate for seats provided upon opposite sides of itslongitudinal center line with projections of varying height and ofvarying distances from said line and adapted to accommodate between themtions being arranged in sets of four of corcenter line.

3. A reinforcing plate for a seat provided upon opposite sides of itslongitudinal center line with projections of varying height and ofvarying distances from said line, and adapted to cooperate with eachother in sets of four to accommodate spring arms of dif ferent width,said projections formed from portions of the plate partly severedtherefrom on lines parallel to the longitudinal center line of theplate.

4. In an agricultural seat, the combination of a seat member and areinforcing plate therefor, the seat member formed with tubular eyeletsdrawn from the metal of the seat member and the reinforcing plate formedwith corresponding holes to receive said eyelets and secured to the seatmember by heading the eyelets upon the underside of the reinforcingplate.

5. In an agricultural seat, the combinaaperture for the securing boltand with an annular corrugation around the same and forming a depressionfor seating the head of the bolt, a reinforcing plate provided with aannular corrugation, means securing the seat member and reinforcingplate together and comprising tubular rivets drawn from the metal of theseat member and engaging in apertures of the reinforcing plate,projections formed of the reinforcing plate on opposite side of thelongitudinal center line of the plate and adapted to prevent the seatfrom turning on the supporting spring, and lips formed at the edges ofthe reinforcing plate and adapted to hold a supporting spring arm out ofcontact with intervening parts. 7

6. In an agricultural seat, the combination of a seat member and areinforcing plate secured to the underside of the seat member andprovided with projections upon its underside of varying height and ofvarying distance from the longitudinal center line porting bars ofdifferent "width and prevent the seatmember from turning thereon, saidprojections being formed in groups on opposite sides of the longitudinalcenter line by slitting the plate and depressing the metal on one sideof the slits.

7. A reinforcing plate secured to the unl derside of the seat andprovided upon its spring arms of difierent width, said projec respondingheight and distance from. the

tion of a seat member formed with a central corresponding bolt hole anda corresponding adapted to accommodate between them supunderside withsets of projections of graduated distances from both the longitudinaland the transverse center lines of the plate and of a graduated heightaccording to their distances from said lines, said projections adaptedto accommodate supportlng bars of different sizes in both of saiddirections and prevent the seat from turning upon said bars.

In testimony whereof I aflix my signature in presence of two Witnesses.
